Motor protection method and device of washing machine, washing machine and storage medium

The invention discloses a motor protection method and device for a washing machine, the washing machine and a storage medium, and the method comprises the steps: obtaining the operation parameters of a motor in the operation process of the motor of the washing machine after the washing machine is started; determining an operation stage of the motor; if the operation stage of the motor is a washing stage, the operation mode of the motor is controlled according to the operation parameters of the motor based on at least one of a first set threshold value, a second set threshold value and a third set threshold value, so that protection control over the motor in the washing stage is achieved; if the operation stage of the motor is the dehydration stage, the operation mode of the motor is controlled based on at least one of a fourth set threshold value and a fifth set threshold value, so that protection control over the motor in the dehydration stage is achieved. According to the scheme, the operation parameters of
